Reginald Hargreeves was never a trustworthy person, which is why when he said he had a 'plan' you didn't trust him. However, you still went with the others after Luther was killed, but you ended up getting lost, as if you were going in a loop around the corridors of the hotel. As you walked through another door, you finally spotted Five. He seemed to be stuck in the same situation as you, having just been walking around the corridors and trying to find a way out. He spotted you after a brief moment of looking around.

"Finally, someone else. I don't trust this place." He says, walking up to you. He seemed confused but also angry at the fact that he was stuck in here, but seemed to slightly relax when he saw you.
